Area Forecast Discussion
National Weather Service Paducah KY
615 PM CDT SAT JUL 9 2016

.UPDATE...
Issued at 615 PM CDT Sat Jul 9 2016

Updated for 00Z aviation forecast discussion.

.SHORT TERM...(Tonight through Monday night)
Issued at 332 PM CDT Sat Jul 9 2016

Zone of instability over SEMO is area being monitored for late day
and evening convection. It appears the axis will be from roughly
Reynolds County MO southeast toward New Madrid. This could shift a
little farther east with any late day sun. The activity should
diminish this evening. Instability is reasonable, but the overall
flow is much weaker. Thus organization will be limited and
coverage more isolated/scattered. A pulse strong to severe storm
cannot be ruled out. But not like what we've seen the last 3 days.
Lower confidence forecast late tonight into Sunday for isolated
convection over the west 1/2 of the area, especially SEMO. Will
keep 20 percents going, and mainly diurnally driven Sunday. Will
go dry Sunday night and Monday night, with a chance of convection
Monday mainly southern 2/3 of the area, in line with the ECMWF.
NAM not showing so much. But a signal has been there for Monday
for more than 1 day. Temps will continue to be persistence based
as the going numbers line up with MOS and base model output.
Overall model preference in the near term was a blend of the HRRR
and NAMnest hourly data, GFS 3 hourly data. Longer term, more
weight was given to the ECMWF.

.LONG TERM...(Tuesday through Saturday)
Issued at 332 PM CDT Sat Jul 9 2016

The medium range models/ensembles seemed to have come into a little
better agreement in their solutions for the extended forecast.
However, the finer details are more murky.

At the start of the extended period, persistent southwesterly low
level flow will tend to maintain a moist and unstable atmosphere
under weak ridging aloft. Scattered, mostly diurnal showers and
tstms can be expected Tuesday and Wednesday as the flow aloft
becomes more zonal. Pcpn chances may be a bit more concentrated in
the north Wednesday due to minor mid level shortwave energy moving
through.

Probabilities of pcpn should ramp up some Wednesday night and
Thursday across the PAH forecast area, associated with a more robust
mid level lobe of energy to the south of an opening wave skirting
the southern Canadian border. At this time frame, 50% PoPs seemed
appropriate for daytime Thursday. A wind shift should occur Thursday
night, ushering somewhat cooler/drier air into mainly the
northeastern half of the PAH forecast area for Friday and Saturday.
Under increased flow aloft however, ripples in the flow will be
conducive to periodic MCS development across the central Plains and
into our region. We will maintain chance PoPs through Day 7.

.AVIATION...
Issued at 615 PM CDT Sat Jul 9 2016

Will have a scattered cu deck below occasional high clouds. Winds
will become light or calm tonight. There is a chance of fog
overnight and that is reflected in the TAFs. Any fog would burn
off quickly Sunday morning. Convection should stay west of the
TAF sites through the evening. Low level moisture in place on
Sunday will allow for some cumulus mainly south of KEVV.
